to exit the Programming Mode. To change the previously entered data in any field, enter it from the keypad or, in the
case of the unit weight you can use the scale to sample for the unit weight. Press the * key after each entry to move to
the next field. Once you’ve completed the reprogramming of the item code, press the
MODE key to save the changes
and exit the Programming Mode.
3. The display will prompt you to enter a tare weight for this item by displaying tare in the Weight
column. The tare weight is limited to 5 digits plus the decimal symbol and must be entered numerically
(i.e. you cannot place a container on the platform in the Item Programming Mode and press the TARE
key). Note that if you enter a tare weight here to be associated in memory with this Item Code, when you
recall an Item Code this stored Tare Weight will override any Tare Weight you have digitally entered into
the scale or entered using the TARE key. Press the * key to store the tare weight and move to the Unit
Weight.
4. Enter Unit Weight (refer to Section 5.5). The unit weight is limited to 5 digits plus the decimal symbol.
This can be done by sampling if the unit weight is unknow
n or by digital entry if known. Press the * key
to store the unit weight and move to the programming of the setpoints.
5. SPEC 04, Bits 1 and 0 - Setpoint Type determines what type of setpoint you are programming: 00: %
Quantity
, 01: % Weight, 10: Quantity, or 11: Weight. The setpoints are programmed by entering and
storing a value (Setpoint 1) and then entering and storing a percentage or amount (Setpoint 2). Enter the
value for Setpoint 1 (Ex. 100 pcs) and press the * key to advance to Setpoint 2. (For instructions on how
to program Customer specifications, see Table 3.2.1.)
6. Enter a value for Setpoint 2 (Ex. 85%) and press the * key to store the value and complete
the
programming cycle for this item number.
NOTE:
•There are four types of setpoints which can be selected by setting SPEC 04, Bits 1 and 0: % of Quantity (%QTY), % of Weight
(%WT), Over/Under Quantity (QTY), or Over/Under Weight (WT).
• When entering weight setpoints, be sure that you enter in the weight values with decimal point and all leading and trailing zeros.
• All percentage values must be rounded
to the nearest whole number, fractional percentages are not allowed.
• Setpoints involving % of quantity or weight are limited by the dec
imal places available on the display. For example: if Set Point
value 1 specifies a Quantity of 9999999, then a Set Point value 2 of % of Quantity cannot be set for more than 100% because all
7 digits of the display are already in use.
Table 6-2 below shows what to enter in each of the two set point va
lues to program each type of set point. The alarm sounds
with a rhythmic beeping at setpoint one and with a rapid beeping at setpoint two. Fo
r the Setpoint Alarm to be activated, SPEC
02: SET POINT ALARM must be set to “0: ON”. See Section 3.2.1 for instructions on how to se
t Customer specifications.).
Here are some examples of how the setpoints can be programmed. These examples can be adjusted to fit your
application.
7. If you wish to program another Item Code’s informa
tion, enter a new Item Code and press the * key.
8. When you are finished programming ite
m codes, press the MODE key to exit the Programming Mode
and return to the Weighing Mode.

Table 6-2. Setpoint Configuration
Setpoint Types % QTY QTY % WEIGHT WT
Setpoint 1 80 pieces (target) 50 pieces 2.0 lb (target) 1.2 lb
Setpoint 2 80% 75 pieces (target) 50% 1.5 lb (target)
Equation 80 x 80% = 64 N/A 2.0 x 50% = 1.0 N/A
Slow Beeping Occurs At 64 pieces 50 pieces 1.0 lb 1.2 lb
Rapid Beeping Occurs At 80 pieces 75 pieces 2.0 lb 1.5 lb
